Starting tomcat server after setting classpath for java

Sorry if this is nothing to do with java, it is more to do with starting tomcat server.
Tomcat server has been working totally fine, but when I wanted to compile a java servlet I wrote for it, I needed to run a BAT file called gojava in MS-DOS that had the classpath for java to work properly. I then attempted to run Tomcat, but just got 'bad command'. As long as I don't start up java by setting the classpath, tomcat will work, but as I need java to write servlets and then to test them without restarting my PC each time, how do I get tomcat to work?
Thanks
Hannah

Sounds like your batch file is changing your path, not your classpath. If you're getting "Bad command or filename" when attempting to run Tomcat, it can't find the executable. Check out the .bat file and see what it's doing (maybe even post it here for further clarity). If it's changing your path at all, make sure it includes a %path% to indicate that it simply wants to append items to the path, not overwrite it completely. Sorry if i'm way off base with my suggestions, but it sounds like that's where the problem's going to be, especially if rebooting resolves the problem.

Set classpath for java in fedora core 1?

i am new to programming java on linux and im having trouble finding out how to set classpath in the shell, permenently. i have the sdk installed and tried the usual "hello world" test and failed. the response i would get a message telling me javac is not a bash command. i have no clue how to set classpaths in linux so i would much appreciate it if someone would show me thanks

Ok, there is two ways to achieve this. Either by setting it globally for all the user, or only for your self. If you are working on your own station and have super user access, you can set it up for all th eusers, if not, just set it for your self. How ??
for all the users, modify the file /etc/profile and include this:
PATH=$PATH:/path/to/jdk/bin:.
CLASSPATH=$CLASSPATH:/path/to/jdk/lib/tools.jar:/path/to/jdk/lib/rt.jar
export PATH CLASSPATH
If you want to add it only for ur self then, modify the lsame line in ~/.bash_profile
hope this helps

to make your life easy i tried to connect..
what you have to do is.. you mysql database server should be running
next you have to download one of the version of mysql driver.. i downloaded mysql-connector-java-5.0.5
go to my computer right click - >advance tab -> click on environment variable -> put you path e.g. C:\Program Files\Java\jarFiles\mysql-connector-java-5.0.5\mysql-connector-java-5.0.5-bin.jar
into your classpath in a user variable section..
Try this code
import java.sql.*;
public class MySqlConnect{
     public static void main(String [] args){
          try{
               Class.forName("com.mysql.jdbc.Driver");
               String url ="jdbc:mysql://localhost:3306/test";
               Connection con =DriverManager.getConnection(url,"root", "password");
               System.out.println("Connection: " + con);
          }catch(ClassNotFoundException cnfe){
               cnfe.printStackTrace();
          }catch(SQLException se){
               se.printStackTrace();

Can I set classpath for OAS 10g?

Hi, 
 
I have OAS on my workstation. Here are the details. 
Server : Oracle Application Server 10g Release 3 
Version : 10.1.3.1.0 SOA4 
Build : 061008.0900.00025 
Platform : Windows XP - SP2 
 
I want to set an explicit classpath for complete OAS 10g as such and not to an individual oc4j application. Will I be able to do it? 
I saw the System Properties after my server started. 
It has a name-value pair as "java.class.path oc4j.jar". 
So, I assume all my classpath settings (done thru Environment Variables from My Computer) are lost.? I want to set it explicitly during the server startup itself. Can I do that? 
I tried setting below in the opmn.xml 
<process-set id="ASG" numprocs="1"> 
<module-data> <category id="start-parameters"> <data id="start-executable" value="C:\Oracle\product\10.1.3.1\OracleAS_1\jdk\bin\java"/> <data id="start-args" value="-classpath C:\abc\properties\"/> 
I appended my properties folder after all the jar files present in that tag. 
But its not loading any of my properties files. 
 
Can someone please help me out. 
 
Regards,

No, the iPad does not support multiple user accounts or preferences.

How to set classpath for J2ME

how to set class path for j2me. I downloaded J2ME Wireless tool kit. And set the classpath "set classpath=c:\J2mewtk\lib\midpapi.zip;.;". but i could compile java file. .how to set.
With regards
Santhosh

When you are downloading j2MEWTK, everything is included within it. You dont require MIDP seperately. When you are runnung the ktoolbar , which is provided with J2mewtk, the preverifier runs and creates the required jad file for you. You dont need a forte to run these.
If you want to download MIDP seperately, that also is possible. Then you have to go for command line arguments. Please refer to Sun's MIDP page for details.
Let me know, if you face any further problem

Setting classpath within java application

Hi
Sorry if this question has already been asked, I've searched for it but couldn't find it.
I've written a class (see below) that when given a directory will add all of the jar files to the classpath.
The classpath is updated to include all of the jar files but if I try to use a class within one of these jar files then an exception is generated stating that the class can't be found.
Can anyone help me with this problem? I thought that I would only need to update the classpath.
Thanks,
Rob
public class Jar {
 public static void addJarsToClasspath(String root) {
 File f = new File(root);
 if (f.exists()) {
 File[] jars = f.listFiles(new FilenameFilter(){
 public boolean accept(File dir, String file) {
 return ((String)dir.getName()+file).endsWith(".jar");
 String classpath = System.getProperty("java.class.path");
 for (int i=0; i<jars.length; i++) {
 classpath = classpath.concat(":"+root+"/"+jars.getName());
 System.setProperty("java.class.path",classpath);
 System.out.println(System.getProperty("java.class.path"));

You can do this with batch files in Windows NT/2000:
1) create a batch file called "setcp.bat" containing the following:
for %%i in (C:\myPath\*.jar) do call appendcp.bat %%i
2) create another batch file called "appendcp.bat" containing the following:
set CLASSPATH=%CLASSPATH%;%1
Now you can run setcp.bat and it will add all JAR files in C:\myPath to your CLASSPATH.

How to set classpath from java class ??

I have tried to use System.setProperty("java.class.path", "my class path string ") to set classpath dynamically. But it is not working. How to set it dynamically from java class ?? Thanks , gary

Look into the java.net.URLClassLoader. You can't set the classpath after the fact but you can specify URL's that will checked when you try to load a class with that loader.

Set classpath from java code

Hi,
Is it possible to set new classpath from java code? Something like System.setClasspath(String);
Many thanks
Miso

You aren't the first one to wonder whether that would work, so don't call yourself stupid on that account.
Not taking 15 minutes to set up and run a test to actually see if it works... well, if you really needed the answer, that would be different.

Set JAVA_OPTS for Tomcat in unix

Hi all,
I've faced a problem on setting multiple system properties in the JAVA_OPTS for Tomcat in Unix.
Example:
JAVA_OPTS=-Dmypath="/home/" -Dmypath2="/home2/"
I've tried in Windows and it works fine but not sure why in Unix it can't be done. Will be very appreciate if someone can help.

Nope. If your application requires more than one retrieval from System Property, it will require more than one -D in the startup. However, it only works for Windows environment not unix.

Classpath for java packages

I am trying to execute java files which are present in C:\dss\dss_tests\src\src_devTests\com\ti\debug\engine\scripting folder. When I am executing it its shows lot of error because the class path for packages are not set. So, I set the class path C:\dss\dss_tests\lib\com\ti\debug\engine\scripting because all the class files are present in this location. And some of the jar files contain packages and I have given the path where all jar files are present. Still some errors occur due to some unknown packages. I tried to search in all the folders but I couldn?t find that packages.
the errors i am getting is

Please help me on this

Hi kav,
So, I set the class path C:\dss\dss_tests\lib\com\ti\debug\engine\scripting because all the class files are present in this location.How do you set that? You have to set the classpath jar by jar, here is an example of a classpath:
<?xml version="1.0" encoding="UTF-8"?>
<classpath>
 <classpathentry kind="src" path="src"/>
 <classpathentry exported="true" kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER"/>
 <classpathentry kind="lib" path="C:/control/drivers/terajdbc4.jar"/>
 <classpathentry kind="lib" path="C:/control/drivers/activation.jar"/>
 <classpathentry kind="lib" path="C:/control/drivers/commons-net-1.4.1.jar" sourcepath="lib/commons-net-1.4.1"/>
 <classpathentry kind="lib" path="C:/control/drivers/db2java.zip"/>
 <classpathentry kind="lib" path="C:/control/drivers/jakarta-oro-2.0.8.jar"/>
 <classpathentry kind="lib" path="C:/control/drivers/jakarta-regexp-1.5.jar"/>
 <classpathentry kind="lib" path="C:/control/drivers/log4j-1.2.15.jar"/>
 <classpathentry kind="lib" path="C:/control/drivers/mail.jar"/>
 <classpathentry kind="lib" path="C:/control/drivers/sqljdbc.jar"/>
 <classpathentry kind="lib" path="C:/control/drivers/tdgssconfig.jar"/>
 <classpathentry kind="lib" path="C:/control/drivers/tdgssjava.jar"/>
 <classpathentry kind="lib" path="C:/control/drivers/db2jcc.jar"/>
 <classpathentry kind="lib" path="C:/control/drivers/db2jcc_license_cisuz.jar"/>
 <classpathentry kind="lib" path="C:/control/drivers/db2jcc_license_cu.jar"/>
 <classpathentry kind="lib" path="C:/control/drivers/charsets.jar"/>
 <classpathentry kind="output" path="bin"/>
</classpath>I hope it helped!

Classpath for java and javac

Hi,
I'm a bit confused as to when include the "current" path to java/javac's "-classpath". For instance, if the project has the following structure:
test
|___foo (package "foo")
         |___B.java (extends foo.A)
         |___A.javaand the "current" directory is at "test/", then a simple "javac foo/B.java" or "java foo.B" works. However, if the structure of the project is altered to the following:
test
|___foo (package "foo")
|      |___B.java (extends foo.A and imports boo.C)
|      |___A.java
|
|___myapp (just a directory)
          |____boo (package "boo")
                |____C.javathen in order to compile or run foo.B when the current directory is at "test/", I have to explicitly specify the "current" directory (or "."), i.e.
javac -classpath myapp/:. foo/B.java or java -cp myapp/:. foo.B
Why is it that in the first example, the current directory need not to be specified (".") but in the second example, it must? Is it because as soon as "-classpath/-cp" option is included in the command line, java ignores the default current path ("./")?
Sincerely,

If nothing is specified via -cp and no CLASSPATH is set, then the default classpath contains one entry, which is the current directory (a.k.a the classpath is ".").
If you set the classpath, then the classpath is exactly what you set it to and doesn't include any default.
That's the only reasonable way to model such things, because if you included the current directory in all cases, then that would produce many unexpected side effects.
